LENS-MOUNTING FOR EYE GLASSES.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed July 7,1906. Serial No. 325,119-

To all whom it may concern:

Be it known that I, GEORGE BAUSCH, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Lens- Mountings for Eyeglasses, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention relates to certain improvements in mountings foreye-glasses, having more particular reference to the manner of attachingthe bow and nose-piece to the lens-clamp or post.

In applying the nose glasses to the eyes or rather to the nose it iscustomary to spring the bow against its own tension for the purpose ofincreasing the space between the nose pieces so that when released, thenosepieces will more firmly grip the nose, and in some in stances, theconnections between the bow and lens-- clamps or posts have been madespecially resilient by incorporating extra, comparatively light coilsprings. at the junction of the bow with the post or similar part of thelens clamp. That form of mounting, however, adds materially to theexpense of the frame, and owing to the fact that no provision is madefor lateral adjustment, it is necessary to carry a number of sizes instock.

The essential object of my present invention is to produce acomparatively inexpensive mounting in which the relation of the bow andthe posts to which it is attached is such as to produce the desiredresiliency without increasing the number of parts and at the same timeallowing the lenses to be adjusted toward each other to vary thedistance between the nose-pieces so that one bow-piece takes the placeof those of various sizes.

Another object is to mount the nose-piece upon one end of a coil spring,the other end of which is attached to the lens-clamp, the coil beinglocated at one side of the lens while the nose-piece is located at theopposite or inner side, thereby affording the desired degree ofresiliency and clamping tension of the nose-pieces upon the nose.

Other objects and uses will appear in the following description.

.In the drawings.Figure 1 is a face view of my improved mounting showingfragmentary parts of the eye glasses mounted thereon. Figs. 2 and 3 aresectional views taken respectively on lines 2-2 and 33, Fig. 1. Fig. 4is an elevation of the bow-spring.

This mounting consists essentially of a one-piece bow-spring -1-;lens-clamps 2- and nose-pieces 3, which-latter are attached to thelens-clamps 2 through the medium of coil-springs 4.

The bow-spring 1 is made in one piece of comparatively light springmetal having its central portion arched transversely and its endsdisposed in substantially the same straight line, as best seen in Fig.4.

the distance between the inner edges of the lenses so that the ends ofthe spring extend some distance across the inner faces of said lensesand are adjustably secured in suitable posts 5 on the inner portions ofthe clamps 2 some distance beyond the adjacent edges of the lenses so asto afford a comparatively long leverage and consequent increasedresiliency or flexibility of the bow-spring which may be of any suitablecross sectional contour adapted to give the desired resiliency betweenthe bearings or posts -5.

The lens-clamps 2 are substantially identical in construction, eachcomprising opposite ears G and -7 spaced apart a sufficient distance toreceive between them the adjacent edge of the lens a, said ears and lensbeing formed with alined apertures, one of which is threaded forreceiving a suitable screw -8, whereby the ears -6 and 7 are drawnfirmly against opposite faces of the lens. Each clamp 2 is provided withoppositely projecting spurs 9 for engaging the inner edge of the lens tohold said lens against turning upon the screw 8.

The post 5 is preferably formed integral with the inner lens-clampingear 7 and is provided with a guide opening 10- and a threaded aperture11, said guide-opening receiving the adjacent end of the bow-spring 1,while the threaded aperture 11 receives a set screw 12 for securing thelens clamp 2 in its adjusted position upon the end of the bow 1.

It is now obvious that by attaching the ends of the bow spring 1 toposts formed on the inner faces of the lenses some distance beyond theadjacent edges of the latter an extra degree of resiliency is affordedto permit the lenses to be sprung backward and forward to vary thedistance between the nose-pieces 3, thereby facilitating the adjustmentof the lenses and nose-pieces to the eyes and nose respectively.

The coils 4 are identical in construction, and are preferably bothlocated some distance beyond the plane of the lenses, each having oneend attached to one of the lens clamps -2 and its free end extendedtransversely of and to the opposite side of the plane of the lens andattached to or provided with a nose piece, as 3, of any desiredconstruction.

As shown in Figs. 2 and 3, the ends of the bow spring -l andguide-openings 10 which receive the same are angular in cross section toprevent relative turning of the bows and lens clamps.

By making the ends of the bow-springs straight the lens clamps andlenses thereon may be adjusted toward and from each other to a limitedextent, to correspond to different binocular distances or other visualrequirements, after which they may be clamped in their adjustedpositions by the screws 12.

It will be seen from the foregoing description that in This bow-springis of considerably greater length than carrying out the main object ofmy invention, viz: to

"-between'theirinner and outcrends, and nose pieces located I obtain thedesired resiliency with the use of a onepiece bow-spring, I have locatedthe post to which the ends of the how spring are attached within theperiphcry of the lenses, or some distance from their adjacent edges, andhave made the ends of the spring comparatively straight so as to allow alimited adjustment of the lens clamps thereon. In addition to this, Ihave also made the nose-pieces 3 more resilient by attaching it to theend of a coil-spring, as 4 so that the coil is located at one side ofthe plane of the lens while the nose-piece 3- is located at the oppositeside of said plane.

What I claim is:

1. A lens mounting comprising a pair of lens clamps, each having a noseguard connected thereto, and a one piecebow spring having its endsattached at points hetween the nose guards and the outer ends of theclamps.

2.. A lens mounting comprising a pair of lens clamps each having a noseguard connected thereto, and a one ends of the clamps.

3/ A mounting for eye-glasses comprising a pair of-lensclamps-eachattached to one of the lenses and provided wvith a post within theperipherylof the lens, each post having an aperture and a one-piecebow-spring having its ends inserted in the apertures of the posts. 4 Amounting for eye glas'ses comprising a pair of" clamps, each having anose-guard connected there to, -a one piece liowsprin'gfconjnecting-said clamps at points.

inside of the points of attachment of the bow spring with the clamps,the connection of each nose piece with its clamp having a coiled springtherein.

5. A mounting for eye-glasses, comprising a onepiece bow-spring havingits ends extending transversely across the faces of the lenses, a pairof lens clamps each adjustably mounted upon one end of the bowsprings,and means for securing the lens clamps to the ends of the bowspring.

G. A mounting for eyeglasses comprising a bow spring havingsubstantially straight ends extending in the direction of the axis ofthe lens, a pair of lens clamps each adjustably mounted upon one end ofthe bow springs, a pair of nose guards andra pair of springs each havingits ends extending in substantially the same direction transversely ofthe lens, one end of each spring being attached to one nose-guard, andthe other end being attached to the-adjacent lens clamp.

7; A mounting for eyeglasses-comprising a pair of lens clamps, eachhaving an apertured posttwithin the periphery of the lens; a one-pieceboW-spring having its ends inserted in the apertures in said posts, thelens clamp beingadjustable lengthwise'of the ends of the bowspring,means for holding'thelen s'-'clamps in their adjusted position upon saidspring, a pair of nose-pieces and a pair of coilsprings, each having oneend attached to one of the nose-pieces and itsother end attached -to oneof the lensclamps.

In witness whereof have hereunto set my hand this GEORGE BAUscH. Y
